Two business a2 level critical path

The critical path is the longest path through the network. This information may be presented as a table or as a chart. The relationship between these activities can be represented in a precedence table, sometimes called a dependency table.

The total float of any critical activity is always zero. The sequence of tasks which have to be done one after another with no gaps in between is called the Critical Path.

The activities on this path are the critical activities.

Q2 Evaluate the main difficulties faced by Balfour Beatty and other construction companies in their use of CPA to plan Two business a2 level critical path projects. The completion of one or more activities is called an event.

The notation i,j is used to represent the activity between events i and j. Activities often rely on the completion of others before they can be started. There must only be one activity between each pair of events in the network.

Then, the duration of each activity is estimated and these factors are then arranged as a network or graph, showing the whole project from start to finish, and showing Two business a2 level critical path tasks can happen at the same time. The direction of the arrows shows the order in which the activities must be completed.

It is given by: A dummy activity is one that has zero duration. These times are calculated using a backward scan from the terminal vertex back to the start vertex.

A second difficulty of using Critical Path Analysis is that Critical path analysis sets tight deadlines, especially for critical activities. These times are calculated using a forward scan from the start vertex to the terminal vertex. Typically, the purpose of scheduling is to determine the number of workers needed to complete the project in a given time, or to determine the minimum time required for a given number of workers to complete the project.

Notice that B 5 lies between two critical events but it is not a critical activity. One benefit of Critical Path analysis to Balfour Beatty is that it always finds the shortest time possible for completing a complex project. Critical Path Analysis puts a lot of pressure on all employees, which could in turn affect the whole project.

It can be very tempting for the employees to cut corners in order to meet these deadlines, but that can mean quality can suffer.

The critical path is then easily identified. The vertices are numbered from 0 at the start vertex and finishing at the terminal vertex. It is useful to add the information about earliest and latest times to the network.

In the precedence table shown on the right, the figures in brackets represent the duration of each activity, i. Latest event times The latest event time for vertex i is denoted by li and represents the latest time that event i may be left without extending the time for the project.

Construction companies rely on subcontractors to complete certain tasks and for certain equipment to be hired at specific times, so with Critical Path Analysis, a manager could predict the exact time a certain piece of equipment would be needed and book the particular equipment early on to ensure that the company will have it when needed.

After studying this section you should be able to: Critical path analysis puts pressure on mangers to manage effectively and meet deadlines. How to Write a Summary of an Article? Activity networks A complex project may be divided into a number of smaller parts called activities.Jun 02,  · In this A level Business revision tutorial, we go through a worked example of how to construct a critical path diagram - sometimes referred to as a Network D.

Critical path method (CPM): The critical path method is a step-by-step project management technique for process planning that identifies critical and noncritical tasks.

Critical path analysis ("CPA") is a widely-used project management tool that uses network analysis to help project managers to handle complex and time-sensitive operations.
